I too use Plexus once a year. The rest of the time just spray with plain water in a spray bottle until it beads up and starts running down the window, then I just run a soft cotton towel lightly over it until dry.
Along these same lines, while at a local car cruise a couple of weeks ago I was talking with a guy who told me he used the ( 'headlight cleaning kit' the auto stores sell to remove the dull,fogging on the headlights of today's newer cars that set out in the elements), on his very original BB 69 roadster. He said it was yellowed very bad. It is the original dated window. I couldn't believe he tried it, I would have been afraid to try it. Has anyone else tried this technique?

Most of the replies here have been how to restore a window after it has been damaged . The answer to his question is how to clean the window of a brand new top without damaging it. First never wipe a dry window . When I wash my car which is very seldom , I first hose the top and window . Then with some warm water containing very little Dawn soap and a soft cotton cloth using very light pressure I clean the window first then the top . Lightly dry the back window first with a cotton cloth then the top . I've used this method for over forty years on all of my convertibles and never had window damage. The tops go bad at the same time as the windows. Now if you repeatedly fold the top down you will get damage sooner . If you do put the top down make sure you use one of the window pillows that the vendors sell but only use it when the back window is free of dust because the rubbing action of the pillow will scratch the window. All in all the windows are not hard to take care of if you take some care.

Back in the day, I used Simonize car wax to clean and protect the plastic window...inside and out...every time I washed the car. It also helped to block UV rays that tend to age/harden/darken the platic window.
Today, there are many polymer polishes that could do similarly. I think using wax does help keep the plastic flexible; don't know if the polymer polishes will aid flexibility or not.
Whatever you use, if the top will be up and in the sun on occasion, make sure the product will block UV rays.
Microfiber towels are GREAT for washing/drying that plastic window. Flush dirt off with hose FIRST, then wash with MILD soap (not detergent), and dry with microfiber towel. Put protectant on inside AND outside of the plastic window.
